GREASE-CUP.

Application filed March 3, 1915. seriai-no. 11,720.

To all whom it may concern Be it lniown'that l, Vio'ron GA zzoLo, :a,

i citizen of the United States, residing at Stockton, in the county of San-*Joaquin,

'State of California, have invented certain new and useful Improvements 3 in Grease- Cups; and I do declare the following to be a clear,'full, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the ac companying drawings, and tothe characters ofreference marked thereon, which form a part of this application. I This invention relates-toimprovements in grease cups used on friction bearingsof all kinds,'the object of the invention being to.

produce a cup by means of which the grease may be delivered against the bearingin predetermined amounts and in an automatic manner. This automatic feature is controlled by operation of the machine or machinery-of which the lubricated bearing may be a part. i 1 p j A further object of the invention isv to produce a structure in combination with that mentioned above, whereby an independent supply of lubricant may be delivered from the cupmanually and independent of.

the automatic feature and without inter fering with the structure by which the automatic feature iscontrolled.

A still further objectof the invention is to produce asimple'and inexpensive device and yet one which will be exceedingly effective for the purposes-1 for whichit is de-' signed.-

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully-appear by a perusal of the following specificationand'claims.

On the drawings, similarcharacters of reference indicate corresponding partsin the several views. 1 1 7 I I v Figure 11s a side elevation,partly insection, of my improved cup. 7 Fig; 2 is aslde elevation of the same taken at right angles to the side shown in Fig. 1 and being partly broken out and in section.

may be had independently of the automatic delivery.

. R ferring'now 'more particularly to the charactersof reference on the drawings,"the 1 e numeral" 1' designates the cup substantially funnel-shaped at its lower end, asat'Q, and

provided with a central orificed outlet i The numeral 4Vdes1gnates a removable cap screw mounted intothe upper end of the cup 1 and-provided with a central orifice 5 surrounded at its upper end by a cupped-out The numeral 7 designates a piston movable in the cup 1 and provided with a small hole 8 disposed through which is a small; pin 9 of lesser diameter than thehole 8, suchpin 9 having a flanged head 10 at one end and a small cross pin 11 on the other, whereby it is held in position in said hole 8. The

. purpose of this hole 8 and pin 9 is to allow of the easy removal of the'piStOn 7 from the cup." 'VVhen the piston' 7 has been pressed downagainst the "grease, the adhesion and suction of'the sameis such as to make it very hard to remove the piston 7, but by pressing the pin 9 so that 'the head 10 is pressed away from the hole 8,'air may be admitted through said holes to relieve the suction and adhesion between the piston 7 and the grease, whereby such piston 7 may. be easily removed from the cup for-the pur: pose of filling the same or for any other desiredpurposes. 1

The piston 7 is screw mounted upon a threaded pin 12 depending centrally into the cup 1 and havinga square head 18 re movably projecting into a shoulder 14 projecting upwardly-from a disk 15 disposed in the upper end of the cup and having a projecting annular flange 16 around its outer periphery." The disk 15 and its shoulI- der 14 are held in position in the cap 4 by means of anut' 17 threaded on the shoulder I 14 andnormally disposed in the cupped-out recess 6. The shoulder 14has a square projecting head 18 extending abovethe nut 17. By applying a wrench to the head 18 and turningthe same,'t his will turn the shoulder 14 andv the disk15 andsince the square'head '13 projectsinto the shoulder 14, such head and its-pin 12 wi1l be turned. This movement will cause the piston 7 to be advanced onthe thread'edpin 12 to press the grease outof the cup 1 through the outlet?) upon the bearing. -Thisis thejmanually operated structure for delivering any quantity of grease at any desired time.

The automatic delivery of the lubricant in predetermined quantities at predetermined times is controlled by means of the following structure, namely: Disposed on the annular flange 16 is a ratchet wheel 19 having a plurality of tapered'recesses 20 in its inner periphery. Pins 21are disposed in these recesses 20 so that when the.

ratchet wheel 19 is moved in the direction of the arrow shown in Fig. 5,'the pins 21 will wedge into the tapering ends of the recesses 20 and thus engage the ratchet wheel 19 in frictional contact with the disk 15' so that with the movement of said ratchet wheel 19, the disk 15, shoulder l l, and pin 13-12 will be. turned to advance the piston 7 to force the grease through the outlet v3.

The movement of the ratchet wheel 19 is automatically controlled by means ofthe following structure, namely: Formed on the side of the cup 1 is a barrel 22 having a re- .movable screw cap 23 at its lower end and a removable screw cap 246 at its upper end and an inwardly projecting guide shoulder 24: intermediate its length. A pin 25 is pro- 1 vided with a roller 26 at its lower end and projects through the member 23: as a guide and into the barrel 22 and through the guide24. Such pin 25 isprovided with a with a chambered member 30 communicat- 1 ing-from the barrel 22 to thebarrel 29. The barrel 29 has an opening 31 into the cup 1.

Disposed in this barrel'29 is a hollow. pin 32 having a pin 33 at one end PI'OJBCtIIIgj into the end wall of such? barrel 29, the outer end of such pin 32 engaging the end of a i removable cap; 3 l screw mounted in the end of the barrel 29. This cap34 holds-the pin 32 in position and within the hollow pin:

32 is a'spring 35 which is interposed between the bottom of the pin 32 andthe cap .1

34. to hold such pin. 32 in frictional. engagement lengthwise so that it will have no tendency to any backward rotary movement when turned in one direction. The upper end of the pin 25 is slotted, as at36, with a pin 37 projecting across the upper end of the slot.

32.. This collar .40 is provided with a plurality of tapered recesses 41 on its inner'periphery in which are disposed small pins 42 soth'at. when the collar 40 is'moved'in the An arm 39 projects into the 1 slot36 and is provided at its other-end with a collar 40 normally surrounding I the pin.

direction indicated by the arrow at, Fig. 1 1,1

these'pins 42 will wedge between the collar.

40 and the pin 32 to. cause a frictionah ens gagement between-them, whereby, withsu'oh' movement of the collar 40, the pin :32 .will

be moved but when the collar 40 moves in the reverse direction, the .pins 42,, will iroll out of the wedged position and newts-a; free movement of the collar 40 irrespective of the pin 32. Anytendency of the pin132 to follow this return; movement is overcome.

by the-friction spring 35, as set forth above; The pin 32,- ad acent'the opening 31, is provided with asmall-womn gear .43 engaging withthe ratchet whcelz19so that movement I3 of the pin32 isimparte'd tof suchgratchet wheel 19 to move'it Tinathe direction of the arrow: shown in Fig; 5.. V movement of the saidpini 32, the piston ;7

will be moved inthe manner heretofore de;

scribed.. Movement is, imparted to the pin 32 by means of the vertical: movementofithei pin 25 imparted through the arm 39-;and

Hence, with. the

collar 40, as described; This pin 25 is auto: v

maticallym oved by means of a cam PM.

mounted on a shaft 45 driven in any suit= able manner by the machine or machinery to which the bearing-to be lubricatedunay.

beattached. This cam 44 engages the. rolleiv 26?, so that with'each, revolution of the-shaft 45, the pin 25 will be liftedlto operate the piston 7 through the medium. of the struc' ture detailed above After each; lift, the spring 27' will return. it to itslowerposition again.

From the foregoing description be I Seen that there is an automatic deliverysof a predetermined quantity of greasethrough the outlet 3 through each lift of theipin 25:

and a manual delivery of the lubricantwillbe had in any quantitybyturning the head' 18 which. will, by reason .of the. release ofthe;

wedge pins 21, allow thepistonl' to beadvanced without disturbing the automatic structure.-'

From the foregoing description it readily be-seen that I have prod.ucedsuch% a device, assubstantially fulfils the .objectsjof the invention as set forth herein.

While this specificationsets forth -;in deg tail the present. and iprefer-red construction of the device, still in practice, such devia tions from such detail maybe resortedtoias do notform a5 departure from the spirit-of the invention, as defined i byathe appended. claims- 7 3 Having thus described my invention what Iclaim as new and useful and desire to secure by Letters Patent; is z 1 r l 1. .A/ device of 'fthe; character described comprising 1 a g C p having an outlet, :a piston movable in said cup, a p111,=m0vab1e vertically adjacent said cup, anarmengages.
